I agree with Borg Santa. I just checked my Silman Complete Book of Chess Strategy, which lists fourteen "named" mates, but didn't see that one. What your position/mate is closest to is "Morphy's Mate," but that involves a direct check from the bishop on the a2-g7 diagonal.

If it hasn't been named yet, maybe you can name it. Something catchy, like the "Prelate Piledriver" perhaps...
